CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the priority benefit of Korean Patent Application No. 10-2016-0121676, filed on Sep. 22, 2016, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference in its entirety.

BACKGROUND 1. Field

Embodiments of the disclosure relate to an air conditioner, and more particularly, to an air conditioner capable of changing an air discharging method.

2. Description of the Related Art

In general, an air conditioner is an apparatus to adjust temperature, humidity, airflow, distribution, etc. to optimal conditions for human activities by using a cooling cycle. Main components constituting the cooling cycle include a compressor, a condenser, an evaporator, and a blowing fan.

The air conditioner can be classified into a split type air conditioner in which an indoor unit and an outdoor unit are separated and installed, and a window type air conditioner in which an indoor unit and an outdoor unit are installed together in a single cabinet. The indoor unit of the split type air conditioner includes a heat exchanger to heat-exchange air inhaled to the inside of the panel, and a blowing fan to inhale indoor air to the inside of the panel and to again discharge the inhaled air to indoor space. In a typical air conditioner, an indoor unit is designed to minimize a heat exchanger, and to raise Revolutions Per Minute (RPM) of a blowing fan to maximize wind velocity and wind volume. Accordingly, the temperature of discharged air is lowered, and the air forms a narrow and long path to be discharged to indoor space.

Accordingly, when a user gets in direct contact with the discharged air, he/she may feed cold and displeasure, and when he/she does not contact the discharged air, he/she may feel hot and displeasure.

Also, increasing the RPM of the blowing fan in order to obtain high wind velocity results in an increase of noise. Meanwhile, a radiant air conditioner of conditioning air without using any blowing fan requires a large panel in order to obtain the same capability as an air conditioner using a blowing fan. Also, the radiant air conditioner has very low cooling velocity, and requires high construction costs.

SUMMARY

Additional aspects and/or advantages will be set forth in part in the description which follows and, in part, will be apparent from the description, or may be learned by practice of the invention.

Hereinafter, the embodiments according to the present disclosure will be described in detail with reference to the attached drawings.

A cooling cycle constituting the air conditioner may be configured with a compressor, a condenser, an expansion valve, and an evaporator. The cooling cycle may perform a series of processes of compression-condensation-expansion-evaporation so as to heat-exchange high-temperature air with low-temperature refrigerants and then supply low-temperature air to indoor space.

The compressor may compress refrigerant gas to a high-temperature, high-pressure state, and discharge the compressed refrigerant gas to the condenser. The condenser may condense the compressed refrigerant gas to a liquid state, and emit heat to the surroundings during the condensing process. The expansion valve may expand the liquid-state refrigerants in the high-temperature, high-pressure state condensed by the condenser to liquid-state refrigerants in a low-pressure state. The evaporator may evaporate the refrigerants expanded by the expansion valve. The evaporator may achieve a cooling effect through heat-exchange with an object to be cooled using evaporative latent heat of refrigerants, and return the refrigerant gas in the low-temperature, low-pressure state to the compressor. Through the cycle, the air temperature of the indoor space can be adjusted.

An outdoor unit of the air conditioner may be a part of the cooling cycle, configured with a compressor and an outdoor heat exchanger. The expansion valve may be installed in any one of the indoor unit and the outdoor unit, and an indoor heat exchanger may be installed in the indoor unit of the air conditioner.

The present disclosure relates to an air conditioner for cooling indoor space, wherein an outdoor heat exchanger functions as a condenser, and an indoor heat exchanger functions as an evaporator. Hereinafter, for convenience of description, an indoor unit including an indoor heat exchanger will be referred to as an air conditioner, and the indoor heat exchanger will be referred to as a heat exchanger.

FIG. 1 is a perspective view of an air conditioner according to an embodiment of the present disclosure. FIGS. 2, 3 and 4 are views for describing operations of the air conditioner according to the embodiment of the present disclosure.

The air conditioner 1 may include a housing 10, a heat exchanger 20, and a blowing unit 30. The housing 10 may include an inlet 12 and an outlet 14. The heat exchanger 20 may exchange heat with air entering the inside of the housing 10. The blowing unit 30 may circulate air to the inside or outside of the housing 10.

In the current embodiment, the inlet 12 may be formed in the side panels 10 c, and the outlet 14 may be formed in the front panel 10 a. However, the positions of the inlet 12 and the outlet 14 are not limited to these.

The housing 10 may include a blade 16 to guide air blowing through the outlet 14. The blade 16 may be located in the outlet 14 to change a direction of air blowing through the outlet 14 or to block the outlet 14. More specifically, the blade 16 may rotate between a guide position 16 a that is parallel to a blowing direction of blowing air and a closed position 16 b that is perpendicular to the blowing direction of the blowing air.

The blowing unit 30 may include a blowing fan 32. In the current embodiment, the blowing fan 32 may be an axial flow fan, although not limited thereto. The blowing fan 32 may have a configuration of passing air inhaled from the inlet 12 through the heat exchanger 20 and then discharging the air through the outlet 14 or a plurality of holes 44 which will be described later.

The blowing unit 30 may include a motor 34. The motor 34 may apply a rotational force to the blowing fan 32.

The heat exchanger 20 may be disposed within the housing 10 to exchange heat with air entered through the inlet 12. That is, the heat exchanger 20 may absorb or transfer heat from the air entered through the inlet 12. Below the heat exchanger 20, a drain panel 22 may be disposed to collect water condensed by the heat exchanger 20.

The air conditioner 1 may include a discharge plate 40.

The discharge plate 40 may be a portion of the housing 10 or a separate element from the housing 10. In the current embodiment, the discharge plate 40 may be formed on the front panel 10 a of the housing 10. More specifically, the discharge plate 40 may be positioned below the outlet 14. However, the position of the discharge plate 40 is not limited as long as it is formed on at least one of the front surface or the side surface of the housing 10. The discharge plate 40 may include a plate body 42, and a plurality of holes 44 formed in the plate body 42. Air blown by the blowing fan 32 can be discharged to the outside of the housing 10 through the outlet 14 or the plurality of holes 44 formed in the discharge plate 40.

The air conditioner 1 may include a shutter 50. The shutter 50 may be movable inside the housing 10. An air path formed inside the housing 10 may include a first path P1 through which air blown by the blowing fan 32 flows to the outlet 14, and a second path P1 through which air blown by the blowing fan 32 flows to the discharge plate 40. The shutter 50 may close at least one of the first and second paths P1 and P2. To this end, the shutter 50 may have a size corresponding to the width of the outlet 14 or the discharge plate 40. The shutter 50 may be movable between a first position 50 a at which it closes the first path P1, and a second position 50 b at which it closes the second path P2. The first position 50 a of the shutter 50 may be a position at which the shutter 50 blocks the first path P1 in the middle of the first path P1, as shown in FIG. 3, or a position at which the shutter 50 blocks the outlet 14 to close the outlet 14, as shown in FIG. 4. The second position 50 b of the shutter 50 may be a position at which the shutter 50 is located on the back surface of the discharge plate 40, as shown in FIG. 2. A method of moving the shutter 50 is not limited. For example, the shutter 50 may slide between the first position 50 a and the second position 50 b.

Hereinafter, operation of the air conditioner 1 according to the above-described configuration will be described.

First, operation in which air blown by the blowing fan 32 is discharged to the outside of the housing 10 through the outlet 14 will be described.

Referring to FIG. 2, the shutter 50 may be disposed at the second position 50 b to close the second path P2. Air blown by the blowing fan 32 may move along the first path P1 by the shutter 50 blocking the second path P2 without flowing into the plurality of holes 44. Therefore, air blown by the blowing fan 32 may pass through the heat exchanger 20, move along the first path P1, and then be discharged through the outlet 14. In the operation, the blade 16 may be positioned at the guide position 16 a.

The air conditioner 1 may blow heat-exchanged air to the outside of the housing 10 through the outlet 14 to thereby adjust indoor temperature quickly as compared with the case of blowing heat-exchanged air through the plurality of holes 44.

Now, operation in which air blown by the blowing fan 32 is discharged to the outside of the housing 10 through the plurality of holes 44 of the discharge plate 40 will be described.

Referring to FIGS. 3 and 4, the shutter 50 may be located at the first position 50 a to close the first path P1. In this case, air blown by the blowing fan 32 may move along the second path P2 by the shutter 50 blocking the first path P1 without flowing to the outlet 14. Accordingly, the air blown by the blowing fan 32 may pass through the heat exchanger 20, flow along the second path P2, and then be discharged into the plurality of holes 44. In the operation, the blade 16 may be at the closed position 16 b.

The air conditioner 1 may blow heat-exchanged air to the outside of the housing 10 through the plurality of holes 44 of the discharge plate 40 so as to reduce the flow velocity of the blowing air. Thus, the user can be prevented from directly contacting blowing air, thereby feeling satisfaction.

Hereinafter, an air conditioner according to another embodiment of the present disclosure will be described. Hereinafter, descriptions about the same configurations as those described above will be omitted.

FIGS. 5 and 6 are perspective views of an air conditioner according to another embodiment of the present disclosure, and FIGS. 7 and 8 are views for describing operation of the air conditioner according to the other embodiment of the present disclosure.

At this time, the outlet 14 may be closed by the blade 16 located in the closed position 16 b, or by the shutter 50.

The outlet 14 and the discharge plate 240 may open selectively. That is, if the outlet 14 opens, the discharge plate 240 may operate in the closed mode 240 a, and if the outlet 14 is closed, the discharge plate 240 may operate in the open mode 240 b.

Hereinafter, an air conditioner according to another embodiment of the present disclosure will be described. Hereinafter, descriptions about the same configurations as those described above will be omitted.

FIGS. 11A and 11B are views for describing operation of an air conditioner according to another embodiment of the present disclosure.

The discharge plate 240 can operate in a close mode 241 a or an open mode 241 b. In the close mode 241 a, the first plate 242 may be in close contact with the second plate 244. At this time, the first hole 242 a and the second hole 244 a may be alternately arranged. That is, the first holes 242 a may be blocked by the second plate body 244 b of the second plate 244, and the second holes 244 a may be blocked by the first plate body 242 b of the first plate 242.

In the open mode 241 b, the second plate 244 may move in a front-back direction with respect to the first plate 242 so that the first plate 242 is spaced from the second plate 244. That is, air blown from the inner space of the housing 10 may pass through the second holes 244 a of the second plate 244, space formed between the first plate 242 and the second plate 244, and the first holes 242 a of the first plate 242 in this order, and then be discharged to the outside of the housing 10. In the current embodiment, the second plate 244 may move relative to the first plate 242, although not limited thereto. However, for example, the first plate 242 may move relative to the second plate 244, or the first and second plates 242 and 244 may move in opposite directions.

Hereinafter, an air conditioner according to another embodiment of the present disclosure will be described. Hereinafter, descriptions about the same configurations as those described above will be omitted.

FIGS. 12 and 13 are cross-sectional views of an air conditioner according to another embodiment of the present disclosure.

An air conditioner 300 may include a discharge plate 40.

The discharge plate 40 may be a portion of the housing 10, and may be formed along the edge of the outlet 14 to be adjacent to the outlet 14.

The air conditioner 300 may include an auxiliary plate 360 having a plurality of holes 362.

The auxiliary plate 360 may be formed behind the discharge plate 40. The auxiliary plate 360 may be formed along the edge of the outlet 14 behind the discharge plate 40 in such a way to be adjacent to the outlet 14, in correspondence to the discharge plate 40. The auxiliary plate 360 may be located upstream of the discharge plate 40 with respect to a flow path formed from the blowing fan 32 toward the discharge plate 40. Through the configuration, if the outlet 14 is closed, air blown by the blowing fan 32 can pass through the plurality of holes 362 of the auxiliary plate 360 and the plurality of holes 44 of the discharge plate 40, sequentially, and then be discharged to the outside of the housing 10.

Since the blowing air passes through the plurality of holes 362 of the auxiliary plate 360 and the plurality of holes 44 of the discharge plate 40 sequentially, the blowing air can be discharged uniformly with respect to the entire surface of the discharge plate 40. Also, since the auxiliary plate 360 is disposed upstream of the discharge plate 40, dew formation on the discharge plate 40 can be minimized.

Hereinafter, an air conditioner according to another embodiment of the present disclosure will be described. Hereinafter, descriptions about the same configurations as those described above will be omitted.

FIGS. 14 and 15 are views for describing operation of a blade included in an air conditioner according to another embodiment of the present disclosure.

The housing 10 may include a blade 16 to guide air blown through the outlet 14. The blade 16 may be located on the outlet 14 to control a direction of air blown through the outlet 14, or to block the outlet 14. In detail, the blade 16 can rotate between a guide position 16 a at which it is parallel to a blowing direction of blowing air and a closed position 16 b at which it is perpendicular to the blowing direction of the blowing air.

The blade 16 may include a plurality of first blades 17 and at least one second blade 18.

The plurality of first blades 17 may move in a guide position 17 a at which they guide discharged air, and a closed position 17 b at which they blocks the outlet 14. The first blades 17 may be positioned in parallel to a blowing direction of blowing air when they are at the guide position 17 a, and when the first blades 17 are positioned at the closed position, the first blades 17 may block blowing air.

At least one second blade 18 may control the positions of the first blades 17. That is, at least one second blade 18 may enable the first blades 17 to move between the guide position 17 a and the closed position 17 b. When the first blades 17 are at the closed position 17 b, the at least one second blade 18 may block the outlet 14 together with the first blades 17 to block blowing air.

Since the outlet 14 is closed in a dual structure by the first and second blades 17 and 18 as described above, it is possible to efficiently discharge blowing air through the discharge plate 40.

Hereinafter, an air conditioner according to another embodiment of the present disclosure will be described. Hereinafter, descriptions about the same configurations as those described above will be omitted.
